"What Our Gearhead® Experts Are Saying: ""I use this as my go-to active midlayer when I want warmth without overheating. It breathes well on the move, dries quickly after hard efforts, and layers easily under a shell. The fit feels clean and comfortable, and the chest pocket is perfect for stashing small essentials."" We pull on the Tecton Jacket when movement and versatility matter most. Rab designed this lightweight fleece midlayer to keep us comfortable during high-output days in cool conditions, whether we’re hiking steep alpine trails, layering up at the crag, or moving efficiently through mixed terrain. The recycled Thermic fleece offers impressive warmth for its weight while wicking moisture and drying fast when the pace picks up. A close-fitting collar adds welcome protection when temperatures drop, while elasticated cuffs keep layering streamlined. Finished with a reinforced chest pocket for durability and storage, the Tecton Jacket is an easy, low-bulk layer that earns its place in packs year-round."
